We report the slowing of a supersonic beam by elastic reflection from a receding atomic mirror. We use a pulsed supersonic nozzle to generate a 511±9m/s beam of helium that we slow by reflection from a Si(111)-H(1×1) crystal placed on the tip of a spinning rotor. We were able to reduce the velocity of helium by 246m/s and show that the temperature of the slowed beam is lower than 250mK in the comoving frame.
